“…One of the famous applications of SYNAPSE 3D, liver analysis, was originally developed for the simulation of the resection range for hepatectomy [30], and usefulness of the clinical application of the virtual ultrasound software included in liver analysis has also been indicated [31]. And using this software, we can perform colorized fusion system in colored display on the US monitor [32]. There are 2 types of SYNAPSE 3D systems.…”

Purpose: Transcatheter arterial chemoembolization (TACE) is one of the most effective therapeutic options for hepatocellular carcinoma (HCC) and it is important to protect residual liver function after treatment as well as the effect. To reduce the liver function deterioration, we evaluated the automatic software to predict the embolization area of TACE in 3 dimensions. Materials and Methods: Automatic prediction software of embolization area was used in chemoembolization of 7 HCCs. Embolization area of chemoembolization was evaluated within 1 week CT findings after TACE and compared simulated area using automatic prediction software. Results: The maximal diameter of these tumors is in the range 12-42 mm (24.6 ± 9.5 mm). The average time for detecting tumor-feeding branches was 242 s. The total time to detect tumor-feeding branches and simulate the embolization area was 384 s. All cases could detect all tumor-feeding branches of HCC, and the expected embolization area of simulation with automatic prediction software was almost the same as the actual areas, as shown by CT after TACE. Conclusion: This new technology has possibilities to reduce the amount of contrast medium used, protect kidney function, decrease radiation exposure, and improve the therapeutic effect of TACE.

“…Software-assisted planning and simulations are also beneficial for percutaneous ablation. Graphics software (including Advantage Workstation ® (GE Healthcare; Waukesha, WI, USA), SYNAPSE VINCENT ® (Fujifilm Medical; Tokyo, Japan), Ziostation2 ® (Ziosoft Inc.; Tokyo, Japan), AZE Virtual Place ® (Canon Medical; Tokyo, Japan), and BioTrace IO ® (TechsoMed; Rehovot, Israel)) display the following scenarios: a pre-interventional simulation, including the orientation and positioning of a tumor and the optimization of access paths, and a peri-interventional simulation, including predictions of the ablation zone and thermal organ injury [18,19].…”

Thermal ablation therapy, including radiofrequency ablation (RFA) and microwave ablation (MWA), is considered the optimal locoregional treatment for unresectable early-stage hepatocellular carcinomas (HCCs). Percutaneous image-guided ablation is a minimally invasive treatment that is being increasingly performed because it achieves good clinical outcomes with a lower risk of complications. However, the physics and principles of RFA and MWA markedly differ. Although percutaneous thermal ablation under image guidance may be challenging in HCC cases with limited access or a risk of thermal injury, a number of ablative techniques, each of which may be advantageous and disadvantageous for individual cases, are available. Furthermore, even when a HCC is eligible for ablation based on tumor selection and technical factors, additional patient factors may have an impact on whether it is the appropriate treatment choice. Therefore, a basic understanding of the advantages and limitations of each ablation device and imaging guidance technique, respectively, is important. We herein provide an overview of the basic principles of tissue heating in thermal ablation, clinical and laboratory parameters for ablation therapy, preprocedural management, imaging assessments of responses, and early adverse events. We also discuss associated challenges and how they may be overcome using optimized imaging techniques.

“…Ogawa et al [7] reported the efficacy of percutaneous ultrasound (US) examination using a novel, real-time virtual sonography method that collates multiple Digital Imaging and Communications in Medicine (DICOM) data sources and displays reference images in color. They concluded that real-time virtual sonography with color display demonstrates utility in increasing operator comprehension of spatial and positional relationships during percutaneous US examination.…”
